Description

Technical Field

[0001] This solution belongs to the field of fixtures, specifically involving a radial arm support drill fixture clamping device. Background Technology

[0002] Rocker arm supports are generally cast parts with complex shapes and multiple holes. During the machining process, they need to be clamped and fixed.

[0003] A search revealed that a utility model patent with authorization announcement number CN219881864U discloses a rocker arm support drill clamping device, which includes a base. A fixed frame and a movable frame are respectively provided on both sides of the upper end of the base. A fixing mechanism is provided at the upper end of both the fixed frame and the movable frame. A clamping mechanism is provided at one end of each fixing mechanism. A movable groove is provided inside the base, and a driving mechanism is provided inside the movable groove.

[0004] In machining, rocker arm support parts often have irregular shapes, making it difficult for traditional fixtures to hold them stably. Furthermore, the lead screw transmission mechanism of the fixture is prone to wear after long-term use, affecting positioning accuracy. Utility Model Content

[0005] The purpose of this solution is to provide a radial arm support drill chuck clamping device to solve the problems that radial arm support parts usually have irregular shapes, making it difficult for traditional chucks to clamp them stably and requiring complicated adjustments. At the same time, it also solves the problem that the screw drive mechanism of the chuck is prone to wear after long-term use, affecting the positioning accuracy.

[0006] To achieve the above objectives, this solution provides a radial arm support drill chuck clamping device, including a base. A fixed seat is fixedly connected to the upper left side of the base, and a movable seat is slidably connected to the upper right side of the base. A slide block is fixedly connected to the bottom of the movable seat and slidably connected to the interior of the base. A lead screw is installed inside the base via a bearing. The lead screw passes through the slide block and is threadedly connected to the slide block. A rotating wheel is welded onto the lead screw. A self-lubricating mechanism is provided inside the slide block. A U-shaped frame is fixedly connected to both the fixed seat and the movable seat. Two retaining rings are fixedly connected to the vertical part of the U-shaped frame. A rotating roller is rotatably connected between the two retaining rings and rotatably connected to the outside of the U-shaped frame. Multiple irregularly shaped clamping blocks are provided on the circumferential surface of the rotating roller.

[0007] The principle of this solution is as follows: In use, the lead screw is first rotated by the rotating wheel, which drives the slide to move axially, thereby moving the movable seat towards the fixed seat, thus clamping the rocker arm support placed on the base. In addition, by rotating the rotating roller and fixing it with a spring-supported pin, different irregularly shaped clamping blocks can be oriented towards the rocker arm support, thus achieving adaptive clamping for different external shapes of the rocker arm support. Furthermore, while the slide is sliding, the self-lubricating mechanism triggers the push rod to push the inclined block through the slide movement, squeezing the oil storage sponge block to precisely drip lubricating oil through the oil outlet hole to the thread engagement of the lead screw, significantly reducing the wear of transmission components and extending the service life of the clamp.

[0008] The technical advantage of this solution is that by setting a fixed seat and a movable seat, both of which are equipped with rotatable rollers, and multiple rotatable and adjustable irregularly shaped clamping blocks on the rollers, and with the positioning of the irregularly shaped clamping blocks in conjunction with the locking pins and springs, it is possible to achieve adaptive clamping of different external shapes of the rocker arm support.

[0009] By incorporating a self-lubricating mechanism within the lead screw and the slide for moving the movable seat, the self-lubricating mechanism triggers the push rod to push the inclined block through the slide movement, squeezing the oil storage sponge block to precisely drip lubricating oil through the oil outlet hole to the lead screw thread engagement point, significantly reducing wear on transmission components and extending the service life of the fixture.

[0010] Furthermore, the bottom of the slide is provided with ball bearings, which are slidably connected to the inner surface of the base. The ball bearings can reduce the frictional resistance of the slide.

[0011] Furthermore, the rotating roller is internally slidably connected with a locking pin, which engages with the upper retaining ring. A spring is installed inside the rotating roller, with one end fixedly connected to the locking pin and the other end fixedly connected to the inner surface of the rotating roller. Multiple springs and locking pins are provided, and their number and position correspond to the irregularly shaped clamping blocks.

[0012] Furthermore, the self-lubricating mechanism includes a hollow plate fixedly connected inside the slide block. An oil-storing sponge block and an inclined block are slidably connected inside the slide block, with the oil-storing sponge block in contact with both the inclined block and the hollow plate. A top rod is fixedly connected to the inner wall of the base. This self-lubricating mechanism facilitates self-lubrication of the lead screw, preventing excessive wear on the threads between the lead screw and the slide block.

[0013] Furthermore, a sealing ring is embedded in the side of the inclined block, and the sealing ring is slidably connected to the inner surface of the slide. The sealing ring enhances the sealing performance between the inclined block and the slide.

[0014] Furthermore, a guide rod is fixedly connected to the inner wall of the slide block, and the guide rod is slidably connected to the inclined block. A second spring is installed inside the inclined block, with one end of the second spring fixedly connected to the guide rod and the other end fixedly connected to the inner surface of the inclined block. The guide rod and the second spring provide auxiliary repositioning for the inclined block.

[0015] Furthermore, the slide block has an oil outlet hole and a through hole inside. The position of the oil outlet hole corresponds to the position of the lead screw, and the position of the through hole corresponds to the position of the push rod. The oil outlet hole allows lubricating oil to be added to the lead screw, while the through hole allows the push rod to be inserted laterally into the slide block. Attached Figure Description

Detailed Implementation

[0022] The basic implementation examples are as follows: Figures 1-4 The image shows a radial arm support drill chuck clamping device, comprising a base 1, a fixed seat 2 fixedly connected to the upper left side of the base 1, a movable seat 3 slidably connected to the upper right side of the base 1, a slide 4 fixedly connected to the bottom of the movable seat 3, the slide 4 slidably connected to the interior of the base 1, and a ball bearing 41 provided at the bottom of the slide 4, the ball bearing 41 being slidably connected to the inner surface of the base 1. The ball bearing 41 can reduce the frictional resistance of the slide 4. A lead screw 5 is installed inside the base 1 through a bearing, the lead screw 5 passing through the slide 4 and being threadedly connected to the slide 4, and a rotating wheel 6 is welded onto the lead screw 5.

[0023] like Figure 1 , Figure 2 , Figure 3 A U-shaped frame 8 is fixedly connected to both the fixed base 3 and the movable base 2. Two retaining rings 9 are fixedly connected to the vertical part of the U-shaped frame 8. A rotating roller 10 is rotatably connected between the two retaining rings 9 and is rotatably connected to the outside of the U-shaped frame 8. Multiple irregularly shaped clamping blocks 101 are provided on the circumferential surface of the rotating roller 10. The shape of the irregularly shaped clamping blocks 101 can be adjusted according to actual working conditions. A locking pin 11 is slidably connected inside the rotating roller 10, engaging with the upper retaining ring 9. A spring 12 is provided inside the rotating roller 10, with one end fixedly connected to the locking pin 11 and the other end fixedly connected to the inner surface of the rotating roller 10. Multiple springs 12 and locking pins 11 are provided, and their number and position correspond to the irregularly shaped clamping blocks 101.

[0024] like Figure 3 , Figure 4 The slide block 4 is equipped with a self-lubricating mechanism 7. This mechanism facilitates the self-lubrication of the lead screw 5, preventing excessive wear on the threads between the lead screw 5 and the slide block 4. The self-lubricating mechanism 7 includes a hollow plate 71 fixedly connected inside the slide block 4. An oil-storing sponge block 72 and an inclined block 73 are slidably connected inside the slide block 4, with the oil-storing sponge block 72 in contact with both the inclined block 73 and the hollow plate 71. A top rod 78 is fixedly connected to the inner wall of the base 1. A sealing ring 74 is embedded in the side of the inclined block 73, and the sealing ring 74 is slidably connected to the inner surface of the slide block 4. The sealing ring 74 increases the sealing performance between the inclined block 73 and the slide block 4. A guide rod 75 is fixedly connected to the inner wall of the slide block 4, and the guide rod 75 is slidably connected to the inclined block 73. A second spring 76 is installed inside the inclined block 73, with one end fixedly connected to the guide rod 75 and the other end fixedly connected to the inner surface of the inclined block 73. The guide rod 75 and spring 76 assist in the reset of the inclined block 73. The slide 4 has an oil outlet 77 and a through hole 79 inside. The position of the oil outlet 77 corresponds to the position of the lead screw 5, and the position of the through hole 79 corresponds to the position of the push rod 78. The oil outlet 77 allows lubricating oil to be added to the lead screw 5, while the through hole 79 allows the push rod 78 to be inserted laterally into the slide 4.

[0025] The specific implementation process of this utility model is as follows: In use, firstly, the lead screw 5 is rotated by the rotating wheel 6. The lead screw 5 will drive the slide 4 to move in its axial direction, thereby driving the movable seat 3 to move towards the fixed seat 2, so that the rocker arm support placed on the base 1 is clamped. In addition, by rotating the rotating roller 10 and fixing it by the locking pin 11 supported by the spring 12, different irregularly shaped clamping blocks 101 can be oriented towards the rocker arm support, thereby realizing adaptive clamping of different external shapes of the rocker arm support. In addition, while the slide 4 is sliding, the self-lubricating mechanism 7 pushes the inclined block 73 by moving the slide 4 to trigger the top rod 78, squeezing the oil storage sponge block 72 to accurately drip lubricating oil through the oil outlet hole 77 to the thread engagement of the lead screw 5, which significantly reduces the wear of the transmission components and extends the service life of the clamp.

[0026] This solution sets up a fixed seat 2 and a movable seat 3. Both the fixed seat 2 and the movable seat 3 are equipped with rotatable rollers 10. Multiple irregularly shaped clamping blocks 101 are rotatably adjustable on the rollers 10. The irregularly shaped clamping blocks 101, together with the positioning of the locking pins 11 and the springs 12, can achieve adaptive clamping of different external shapes of the rocker arm support.

[0027] By setting a self-lubricating mechanism 7 in the lead screw 5 and the slide 4 for moving the movable seat 3, the self-lubricating mechanism 7 triggers the push rod 78 to push the inclined block 73 through the movement of the slide 4, and squeezes the oil storage sponge block 72 to accurately drip lubricating oil through the oil outlet hole 77 to the thread engagement of the lead screw 5, which significantly reduces the wear of transmission components and extends the service life of the fixture.
